Paste the following code into the Sketch Editor window (it’s similar to the Blink sketch, but the blinks last twice as long): const int ledPin = 13; // LED connected to digital pin 13 void setup() { pinMode(ledPin, OUTPUT); } void loop() { digitalWrite(ledPin, HIGH); // set...
Here’s the full source code:int btstate = 0; void setup() { pinMode(13, OUTPUT); pinMode(11, INPUT); } void loop() { btstate = digitalRead(11); if (btstate == HIGH) { digitalWrite(13, HIGH); } else if (btstate == LOW) { digitalWrite(13, LOW); } } ...
digitalWrite(PC13, LOW); delay(500); } 接着在运行pio run 的终端再输入 platformio run --target upload 来下载一些上传工具并上传,比如stlink的驱动～ 接着你就可以把你的stlink和单片机连在一起,也可以直接使用串口下,直接用usb下也可以。 我们需要改一下下载模式: ...
